A health shake is a blended drink intended to be, or marketed as being, healthful for one to consume. They are a more nutrient rich relative of the Milkshake. Slim-Fast is a prominent example, marketed as a weight loss aid. Bodybuilders sometimes drink a protein shake to help build and repair muscles. Some health shakes are intended as a meal replacement, often as a supposedly healthier alternative to traditional sugar-laden and/or fat-laden breakfasts. However, some health shakes have a greater amount of calories than a plate of pancakes or a cheese omelet. Athletes in training, however, may require more calories and nutrients in their diet than less active people.
Any number of ingredients may be put into a health shake, including superfoods, bee pollen, peanut butter, coconut oil, bean powder, clover sprouts, etc. Health shakes can be quite similar to smoothies, although they are not necessarily chilled and tend to not contain large quantities of fruit.
Green smoothies are a type of health shake or smoothie, made by blending green raw leafy vegetables, such as spinach, kale, swiss chard, collard greens, celery, parsley or broccoli with fruit such as oranges, kiwis, apples, mangoes, pears, and bananas, some of which may be frozen, and water or ice. To balance flavor and nutrition the typical ratio in a green smoothie is about 60% fruit to 40% leafy greens.
Companies have begun producing green smoothies or green juice drinks; these products may be pasteurized. At least one blender company has ads which specifically target the intention of producing green smoothies with the blender once purchased, which offers a booklet of green smoothie recipes.
